The primary font format for Macintosh is PostScript. The fonts come in two main parts: a screen font (usually in a suitcase) and a printer font. If the font has multiple weights (such as plain, bold, italic, and bold italic), each weight will have a separate printer font.

Make sure you are sending us all parts of a font, as this is one of the most common mistakes (see The 5 most common problems when sending art on disk).

While we recommend using PostScript Type 1 fonts on the Mac, we also accept OpenType, TrueType, and dfont. These will only consist of a single file. Some TrueType fonts can be troublesome to print, so use the other formats when possible.

On the Mac OS 9 or earlier, fonts are usually stored in System > Fonts. In OS X, there are a number of possible locations:
- Home > Library > Fonts
- Library > Fonts
- System > Library > Fonts
- System Folder > Fonts

The primary font format for Window-based computers is TrueType. All of your installed TrueType fonts are usually located in the /WINDOWS/FONTS folder, and contain the .ttf file extension. The filenames can be cryptic, but if you double-click on a font file, you’ll get a preview window so you know you’re copying the right ones. Please do not copy the entire Fonts folder: just copy the individual TrueType font files themselves.

If you own any Adobe products for PC, there may be fonts stored in c:/Program Files/Common Files/Adobe/Fonts.

We can accept Postscript Type 1 fonts for Windows, and they consist of two files: a .pfm file and a .pfb file. You must send in both files in order for us to be able to use the font. Type 1 fonts do not have a set location on your hard drive, but Adobe Type Manager usually stores them in a folder called PSFONTS.

We can also accept OpenType for PC files.
